Self-priming Diaphragm Pump 75 GPD

Depending upon the pistols and fluid chamber configuration inside the Self-priming diaphragm pump, the Repeating vacuum suction process undergoes in the pump that will suck the water even though its position is higher than the liquid level pumped. In this situation, the pump is always can transfer water resources from a lower place.  Operating voltage 24V, working flow 800-1000ml/min, Optimal for water purifiers and water dispensers that use Non-tap water resources.


Most models are designed for intermittent duty, although some models are rated for continuous operation. Effective for recirculation based applications as well. They are ideally suited to work with hydro-pneumatic storage systems but are compatible with most hydraulic shut-off valves as well. These pumps are commonly used with one or more of our flow control components including: pressure switches, tank level controllers, automatic flow restrictors, and timer or electronic shut-off valves.
